Bose introduces SIE2 and SIE2i sport headphones specifically designed for exercise Bose created two new pairs of sport headphones the SIE2 and iOS-specific SIE2i earphones that were designed with active people in mind. They are the first in-ear headphones specifically engineered for exercise that the US audio firm has offered us. The couple of models are much more colourful than the average Bose headphone. The step-up SIE2i comes in green or orange meanwhile the SIE2 is just available in green. The new devices will come with exclusive Reebok fitness armbands that you can strap your phone or digital music player to your arm. Both of them are high in stability, durability, sweat and water-resistance. The two sets of headphones are also covered with a hydrophobic cloth to keep moisture out while letting sound pass through. Moreover, the SIE2 and SIE2i use different sized (small, medium and large) StayHear tips that comfortably fit the ear without causing irritation. The Bose SIE2 is available in green only. It is in a sport-inspired design that complements any athlete's workout, from casual gym-goers to cross-trainers and avid runners. The pair of headphones are also compatible with most music players, costing $119.95.
